Stereo-view representation of the fitting of atomic models of IF2mt and P/I tRNA into the corresponding cryo-EM densities. The cryo-EM densities are shown as meshwork. The color codes used for various domains of IF2mt are the same as in Fig. 1A. Asterisk (*) points to the region that would correspond to domain III of IF2mt and is not present in our composite homology model.
